The calculations were performed using the first-principles pseudo-potential method within the framework of spin density functional theory (DFT). Our calculations predict that for Bi concentrations greater than ~70%, the WZ structure is more favorable than the NaCl one and that for x = 0 (pure MgO), x = 0.25 and x = 0.50 of Bi concentration the NaCl structure is more favorable than the WZ one. For x = 0.75 of Bi, a transition from wurtzite towards NaCl is possible, when the pressure is about 22 GPa. Also It has been observed the crystal lattice constant closely follows Vegard’s law, that the bulk modulus and the cohesion energy decrease with the concentration x of Bi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=Mg1-xBixO" title=" Mg1-xBixO"> Mg1-xBixO</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo-potential" title=" pseudo-potential"> pseudo-potential</a>, <a href="https://publications.waset.org/abstracts/search?q=rock-salt" title=" rock-salt"> rock-salt</a>, <a href="https://publications.waset.org/abstracts/search?q=wurtzite" title=" wurtzite"> wurtzite</a> </p> <a href="https://publications.waset.org/abstracts/24781/first-principles-investigation-of-the-structural-and-electronic-properties-of-mg1-xbixo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">525</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1134</span> Clinical and Epidemiological Profile of Patients with Chronic Obstructive Pulmonary Disease in a Medical Institution from the City of Medellin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andres%20Agudelo-Velez">Camilo Andres Agudelo-Velez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Martinez-Sanchez"> Lina María Martinez-Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla-Hernandez"> Natalia Perilla-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20De%20Los%20Angeles%20Rodriguez-Gazquez"> Maria De Los Angeles Rodriguez-Gazquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hernandez-Restrepo"> Felipe Hernandez-Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Andrea%20Quintero-Moreno"> Dayana Andrea Quintero-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mejia"> Camilo Ruiz-Mejia</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz-Trujillo"> Isabel Cristina Ortiz-Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Maria%20Zuluaga-Quintero"> Monica Maria Zuluaga-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chronic obstructive pulmonary disease is common condition, characterized by a persistent blockage of airflow, partially reversible and progressive, that represents 5% of total deaths around the world, and it is expected to become the third leading cause of death by 2030.

Agave sap is rich in glucose, sucrose and fructooligosaccharides, and strongly differs from agave syrup from A. tequilana, which is mostly a high molecular weight fructan. Agave sap is converted into pulque by a highly diverse microbial community which includes bacteria, yeast and even filamentous fungi. The bacterial diversity has been recently studied. But the composition of consortia derived from directed enrichments differs sharply from the whole fermentative consortium. Using classical microbiology methods, and selective liquid and solid media formulations, either bacterial or fungal consortia were developed and analyzed. Bacterial consortia able to catabolize specific prebiotic saccharides were selected and preserved for future developments. Different media formulations, selective for bacterial genera such as Bifidobacterium, Lactobacillus, Pediococcus, Lactococcus and Enterococcus were also used. For yeast, specific media, osmotic pressure and unique carbon sources were used as selective agents. Results show that most groups are represented in the enrichment cultures; although very few are recoverable from the whole consortium in artisanal pulque. Diversity and abundance vary among consortia. Potential bacterial probiotics obtained from agave sap and agave juices show tolerance to hydrochloric acid, as well as strong antimicrobial activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agave" title="Agave">Agave</a>, <a href="https://publications.waset.org/abstracts/search?q=pulque" title=" pulque"> pulque</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20consortia" title=" microbial consortia"> microbial consortia</a>, <a href="https://publications.waset.org/abstracts/search?q=prebiotic%20activity" title=" prebiotic activity"> prebiotic activity</a> </p> <a href="https://publications.waset.org/abstracts/17953/culturable-microbial-diversity-of-agave-artisanal-fermentations-from-central-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1132</span> Effect of the Magnetite Nanoparticles Concentration on Biogas and Methane Production from Chicken Litter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guadalupe%20Stefanny%20Aguilar-Moreno">Guadalupe Stefanny Aguilar-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Angel%20Aguilar-Mendez"> Miguel Angel Aguilar-Mendez</a>, <a href="https://publications.waset.org/abstracts/search?q=Teodoro%20Espinosa-Solares"> Teodoro Espinosa-Solares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the agricultural sector, one of the main emitters of greenhouse gases is manure management, which has been increased considerably in recent years. Biogas is an energy source that can be produced from different organic materials through anaerobic digestion (AD); however, production efficiency is still low. Several techniques have been studied to increase its performance, such as co-digestion, the variation of digestion conditions, and nanomaterials used. Therefore, the aim of this investigation was to evaluate the effect of magnetite nanoparticles (NPs) concentration, synthesized by co-precipitation, on the biogas and methane production in AD using chicken litter as a substrate. Synthesis of NPs was performed according to the co-precipitation method, for which a fractional factorial experimental design 25⁻² with two replications was used. The study factors were concentrations (precursors and passivating), time of sonication and dissolution temperatures, and the response variables were size, hydrodynamic diameter (HD) and zeta potential. Subsequently, the treatment that presented the smallest NPs was chosen for their use on AD. The AD was established in serological bottles with a working volume of 250 mL, incubated at 36 ± 1 °C for 80 days. The treatments consisted of the addition of different concentrations of NPs in the microcosms: chicken litter only (control), 20 mg∙L⁻¹ of NPs + chicken litter, 40 mg∙L⁻¹ of NPs + chicken litter and 60 mg∙L⁻¹ of NPs + chicken litter, all by triplicate. Methane and biogas production were evaluated daily. The smallest HD (49.5 nm) and the most stable NPs (21.22 mV) were obtained with the highest passivating concentration and the lower precursors dissolution temperature, which were the only factors that had a significant effect on the HD. In the transmission electron microscopy performed to these NPs, an average size of 4.2 ± 0.73 nm was observed. The highest biogas and methane production was obtained with the treatment that had 20 mg∙L⁻¹ of NPs, being 29.5 and 73.9%, respectively, higher than the control, while the treatment with the highest concentration of NPs was not statistically different from the control. From the above, it can be concluded that the magnetite NPs promote the biogas and methane production in AD; however, high concentrations may cause inhibitory effects among methanogenic microorganisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20sector" title="agricultural sector">agricultural sector</a>, <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title=" anaerobic digestion"> anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a> </p> <a href="https://publications.waset.org/abstracts/114341/effect-of-the-magnetite-nanoparticles-concentration-on-biogas-and-methane-production-from-chicken-litter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1131</span> Clinical and Epidemiological Profile in Patients with Preeclampsia in a Private Institution in Medellin, Colombia 2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez">Camilo Andrés Agudelo Vélez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo"> Isabel Cristina Ortiz Trujillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Evert%20Armando%20Jim%C3%A9nez%20Cotes"> Evert Armando Jiménez Cotes</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Duque%20Restrepo"> Daniel Duque Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Hern%C3%A1ndez%20Restrepo"> Felipe Hernández Restrepo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Andrea%20Quintero%20Moreno"> Dayana Andrea Quintero Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jos%C3%A9%20Builes%20G%C3%B3mez"> Juan José Builes Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz%20Mej%C3%ADa"> Camilo Ruiz Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lucia%20Arango%20G%C3%B3mez"> Ana Lucia Arango Gómez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Preeclampsia is a clinical complication during pregnancy with high incidence in Colombia; therefore, it is important to evaluate the influence of external conditions and medical interventions, in order to promote measures that encourage improvements in the quality of life. Objective: Determine clinical and sociodemographic variables in women with preeclampsia. Methods: This cross-sectional study enrolled 50 patients with the diagnosis of preeclampsia, from a private institution in Medellin, during 2015. We used the software SPSS ver.20 for statistical analysis. For the qualitative variables, we calculated the mean and standard deviation, while, for ordinal and nominal levels of quantitative variables, ratios were estimated. Results: The average age was 26.8±5.9 years. The predominant characteristics were socioeconomic stratum 2 (48%), students (55%), mixed race (46%) and middle school as level of education (38%). As for clinical features, 72% of the cases were mild preeclampsia, and 22% were severe forms. The most common clinical manifestations were edema (46%), headache (62%), and proteinuria (55%). As for the Gyneco-obstetric history, 8% reported previous episodes of this disease and it was the first pregnancy for 60% of the patients. Conclusions: Preeclampsia is a frequent condition in young women; on the other hand, headache and edema were the most common reasons for consultation, therefore, doctors need to be aware of these symptoms in pregnant women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-eclampsia" title="pre-eclampsia">pre-eclampsia</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertension" title=" hypertension"> hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy%20complications" title=" pregnancy complications"> pregnancy complications</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal" title=" abdominal"> abdominal</a>, <a href="https://publications.waset.org/abstracts/search?q=edema" title=" edema"> edema</a> </p> <a href="https://publications.waset.org/abstracts/46372/clinical-and-epidemiological-profile-in-patients-with-preeclampsia-in-a-private-institution-in-medellin-colombia-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1130</span> Understanding of the Impact of Technology in Collaborative Programming for Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Selene%20Molina-Moreno">Nadia Selene Molina-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Susana%20Avila-Garcia"> Maria Susana Avila-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Bianchetti"> Marco Bianchetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelina%20Pantoja-Flores"> Marcelina Pantoja-Flores</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visual Programming Tools available are a great tool for introducing children to programming and to develop a skill set for algorithmic thinking.

However, some of the online tools available for programming for children are not designed to allow simultaneous and equitable participation of the team members since they allow only for a single control point. In this paper, a report the work conducted with children playing a user role is presented. A preliminary study to cull ideas, insights, and design considerations for a formal programming course for children aged 8-10 using collaborative learning as a pedagogical approach was conducted. Three setups were provided: 1) lo-fi prototype, 2) PC, 3) a 46' multi-touch single display groupware limited by the application to a single touch entry. Children were interviewed at the end of the sessions in order to know their opinions about teamwork and the different setups defined. Results are mixed regarding the setup, but they agree to like teamwork. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20programming" title=" collaborative programming"> collaborative programming</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20programming" title=" visual programming"> visual programming</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-touch%20tabletop" title=" multi-touch tabletop"> multi-touch tabletop</a>, <a href="https://publications.waset.org/abstracts/search?q=lo-fi%20prototype" title=" lo-fi prototype"> lo-fi prototype</a> </p> <a href="https://publications.waset.org/abstracts/71685/understanding-of-the-impact-of-technology-in-collaborative-programming-for-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71685.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1129</span> The Conception of the Students about the Presence of Mental Illness at School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aline%20Giardin">Aline Giardin</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Rosa%20Chitolina"> Maria Rosa Chitolina</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Catarina%20Zanini"> Maria Catarina Zanini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyze the conceptions of high school students about mental health issues, and discuss the creation of mental basic health programs in schools. We base our findings in a quantitative survey carried out by us with 156 high school students of CTISM (Colégio Técnico Industrial de Santa Maria) school, located in Santa Maria city, Brazil. We have found that: (a) 28 students relate the subject ‘mental health’ with psychiatric hospitals and lunatic asylums; (b) 28 students have relatives affected by mental diseases; (c) 76 students believe that mental patients, if treated, can live a healthy life; (d) depression, schizophrenia and bipolar disorder are the most cited diseases; (e) 84 students have contact with mental patients, but know nothing about the disease; (f) 123 students have never been instructed about mental diseases while in the school; and (g) 135 students think that a mental health program would be important in the school. We argue that these numbers reflect a vision of mental health that can be related to the reductionist education still present in schools and to the lack of integration between health professionals, sciences teachers, and students. Furthermore, this vision can also be related to a stigmatization process, which interferes with the interactions and with the representations regarding mental disorders and mental patients in society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title="mental health">mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=schools" title=" schools"> schools</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20illness" title=" mental illness"> mental illness</a>, <a href="https://publications.waset.org/abstracts/search?q=conception" title=" conception"> conception</a> </p> <a href="https://publications.waset.org/abstracts/60013/the-conception-of-the-students-about-the-presence-of-mental-illness-at-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60013.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1128</span> Transcultural Study on Social Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martha%20Serrano-Arias">Martha Serrano-Arias</a>, <a href="https://publications.waset.org/abstracts/search?q=Martha%20Fr%C3%ADas-Armenta"> Martha Frías-Armenta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Significant results have been found both supporting universality of emotion recognition and cultural background influence.

Yambao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Philippines is a tectonically active archipelagic country situated near the Circum-Pacific Belt. Hence, seismic hazard assessments are important in the nation-building. In 2014, the Philippines Institute of Volcanology and Seismology (PHIVOLCS) mapped a 12-km NW-trending unnamed active fault near Boso-Boso River, Rizal. Given the limited nature of their technical report, they would like to further consolidate relevant data about this fault. As such, this study aims to characterize the surface and subsurface expression of the fault along Boso-Boso River using rangefront morphology, structural criteria, and ground penetrating radar. This fault is subdivided into two segments: the first segment located in the city of Antipolo is mainly manifested in the upper Kinabuan Formation and terminating near Mt. Qutago, and the second segment in Baras, Pinugay, Rizal cuts through recent fluvial deposits and to the Guadalupe Formation. IfSAR-derived DTM data reveals the morphological expression of the fault defined by offset streams and ridges, linear sidehill valleys, and linear valleys. Fault gouges, fault breccia, transtentional flower structures, slickensides, and other shear sense markers observed in the units of the upper Cretaceous Kinabuan Formation indicate a sinistral sense of displacement. GPR radargram profiles revealed the presence of displacement in reflectors at 3-5 meters below the surface which may be suggestive of the fault within the area. Finally, the fault in Boso-Boso river may be a segment of the larger sinistral Montalban Fault in the north or largely affected by the movement from the Marikina Valley Fault System. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NW%20unnamed%20fault" title="NW unnamed fault">NW unnamed fault</a>, <a href="https://publications.waset.org/abstracts/search?q=range-front%20morphology" title=" range-front morphology"> range-front morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20sense%20markers" title=" shear sense markers"> shear sense markers</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20penetrating%20radar" title=" ground penetrating radar"> ground penetrating radar</a>, <a href="https://publications.waset.org/abstracts/search?q=boso-boso%20river" title=" boso-boso river"> boso-boso river</a>, <a href="https://publications.waset.org/abstracts/search?q=antipolo" title=" antipolo"> antipolo</a> </p> <a href="https://publications.waset.org/abstracts/180046/surface-and-subsurface-characterization-of-a-fault-along-boso-boso-river-rizal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180046.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1126</span> Electromagnetic Fields Characterization of an Urban Area in Lagos De Moreno Mexico and Its Correlation with Public Health Hazards</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Vinicio%20F%C3%A9lix%20Lerma">Marco Vinicio Félix Lerma</a>, <a href="https://publications.waset.org/abstracts/search?q=Efrain%20Rubio%20Rosas"> Efrain Rubio Rosas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Ricardez%20Rueda"> Fernando Ricardez Rueda</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Manuel%20Casta%C3%B1o%20Meneses"> Victor Manuel Castaño Meneses</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reports a spectral analysis of the exposure levels of radiofrequency electromagnetic fields originating from a wide variety of telecommunications sources present in an urban area of Lagos de Moreno, Jalisco, Mexico. The electromagnetic characterization of the urban zone under study was carried out by measurements in 118 sites. Measurements of TETRA,ISM434, LTE800, ISM868, GSM900, GSM1800, 3G UMTS,4G UMTS, Wlan2.4, LTE2.6, DECT, VHF Television and FM radio signals were performed at distances ranging over 10 to 1000m from 87 broadcasting towers concentrated in an urban area of about 3 hectares. The aim of these measurements is the evaluation of the electromagnetic fields power levels generated by communication systems because of their interaction with the human body. We found that in certain regions the general public exposure limits determined by ICNIRP (International Commission of Non Ionizing Radiation Protection) are overpassed from 5% up to 61% of the upper values, indicating an imminent health public hazard, whereas in other regions we found that these limits are not overpassed. This work proposes an electromagnetic pollution classification for urban zones according with ICNIRP standards. We conclude that the urban zone under study presents diverse levels of pollution and that in certain regions an electromagnetic shielding solution is needed in order to safeguard the health of the population that lives there. A practical solution in the form of paint coatings and fiber curtains for the buildings present in this zone is also proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20field" title="electromagnetic field">electromagnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=telecommunication%20systems" title=" telecommunication systems"> telecommunication systems</a>, <a href="https://publications.waset.org/abstracts/search?q=electropollution" title=" electropollution"> electropollution</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20hazards" title=" health hazards"> health hazards</a> </p> <a href="https://publications.waset.org/abstracts/46590/electromagnetic-fields-characterization-of-an-urban-area-in-lagos-de-moreno-mexico-and-its-correlation-with-public-health-hazards" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46590.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1125</span> Comparative Analysis of the Performance Between Public and Private Companies: Explanatory Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atziri%20Moreno%20Vite">Atziri Moreno Vite</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Silva%20Guti%C3%A9rrez"> David Silva Gutiérrez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil companies have become the key player in the world energy scenario thanks to their strong control of the level of hydrocarbon reserves and production.

Production activities are controlled by a derivation of the Hedging Point Policy, and given that the system is subject to deterioration, it reduces progressively its capacity to satisfy product demand. Multiple deterioration effects are considered, reflected mainly in the quality of the parts produced and the reliability of the machine. Subcontracting is available as support to satisfy product demand; also overhaul maintenance can be conducted to reduce the effects of deterioration. The main objective of the research is to determine simultaneously the production, maintenance and subcontracting rate which minimize the total incurred cost. A stochastic dynamic programming model is developed and solved through a simulation-based approach composed of statistical analysis and optimization with the response surface methodology. The obtained results highlight the strong interactions between production, deterioration and quality which justify the development of an integrated model. A numerical example and a sensitivity analysis are presented to validate our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=subcontracting" title="subcontracting">subcontracting</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20control" title=" optimal control"> optimal control</a>, <a href="https://publications.waset.org/abstracts/search?q=deterioration" title=" deterioration"> deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/31365/a-simulation-optimization-approach-to-control-production-subcontracting-and-maintenance-decisions-for-a-deteriorating-production-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31365.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1123</span> Cultural Studies in the Immigration Movements: Memories and Social Collectives </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Eugenia%20Peltzer">María Eugenia Peltzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Estela%20Rodr%C3%ADguez"> María Estela Rodríguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents an approach to the cultural aspects of the Immigrants as part of the Cultural Intangible Heritage of Argentina.

The handle combines the so-called power-grip and accurate-grip in order to provide strength and accuracy in the performance of surgery. The handle is tested using both objective and subjective approaches. The objective approach uses motion capture techniques to obtain the angles of forearm, arm, wrist and hand. The muscular effort is obtained with electromyography electrodes. On the other hand, a subjective survey has been carried out using questionnaires.

It causes negative effects on aquatic organisms and human health. Heavy metals concentrations of chromium, mercury, lead, copper, arsenic, zinc, cadmium, and nickel were investigated in Sta. Maria river, in Laguna. A total of 16 sediment samples were collected from the river at four stations. Atomic absorption spectroscopy (AAS) was used for element detection. It is found that copper is associated with chromium based on statistical analysis using principal component analysis (PCA). Conduct of Sediment Quality Guideline (SQG) revealed that chromium has high toxicity due to values higher than Sediment Quality Guidelines Probable Effect Level (SQG’s PEL). Copper, Nickel, and Pb fall on average toxicity while others are below PEL and effect range low (ERL). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutants" title=" pollutants"> pollutants</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20quality%20guidelines" title=" sediment quality guidelines"> sediment quality guidelines</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20absorption%20spectroscopy" title=" atomic absorption spectroscopy"> atomic absorption spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/146453/heavy-metal-concentrations-in-sediments-of-sta-maria-river-laguna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146453.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1120</span> Self-Esteem on University Students by Gender and Branch of Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Casero%20Mart%C3%ADnez">Antonio Casero Martínez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20Lluch%20Rayo%20Llinas"> María de Lluch Rayo Llinas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is part of an investigation into the relationship between romantic love and self-esteem in college students, performed by the students of matter "methods and techniques of social research", of the Master Gender at the University of Balearic Islands, during 2014-2015. In particular, we have investigated the relationships that may exist between self-esteem, gender and field of study. They are known as gender differences in self-esteem, and the relationship between gender and branch of study observed annually by the distribution of enrolment in universities. Therefore, in this part of the study, we focused the spotlight on the differences in self-esteem between the sexes through the various branches of study. The study sample consists of 726 individuals (304 men and 422 women) from 30 undergraduate degrees that the University of the Balearic Islands offers on its campus in 2014-2015, academic year. The average age of men was 21.9 years and 21.7 years for women. The sampling procedure used was random sampling stratified by degree, simple affixation, giving a sampling error of 3.6% for the whole sample, with a confidence level of 95% under the most unfavorable situation (p = q). The Spanish translation of the Rosenberg Self-Esteen Scale (RSE), by Atienza, Moreno and Balaguer was applied. The psychometric properties of translation reach a test-retest reliability of 0.80 and an internal consistency between 0.76 and 0.87. In this paper we have obtained an internal consistency of 0.82. The results confirm the expected differences in self-esteem by gender, although not in all branches of study. Mean levels of self-esteem in women are lower in all branches of study, reaching statistical significance in the field of Science, Social Sciences and Law, and Engineering and Architecture. However, analysed the variability of self-esteem by the branch of study within each gender, the results show independence in the case of men, whereas in the case of women find statistically significant differences, arising from lower self-esteem of Arts and Humanities students vs. the Social and legal Sciences students. These findings confirm the results of numerous investigations in which the levels of female self-esteem appears always below the male, suggesting that perhaps we should consider separately the two populations rather than continually emphasize the difference. The branch of study, for its part has not appeared as an explanatory factor of relevance, beyond detected the largest absolute difference between gender in the technical branch, one in which women are historically a minority, ergo, are no disciplinary or academic characteristics which would explain the differences, but the differentiated social context that occurs within it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=study%20branch" title="study branch">study branch</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=applied%20psychology" title=" applied psychology"> applied psychology</a> </p> <a href="https://publications.waset.org/abstracts/27333/self-esteem-on-university-students-by-gender-and-branch-of-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">465</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1119</span> Auditory Brainstem Response in Wave VI for the Detection of Learning Disabilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Isabel%20Garcia-Planas">Maria Isabel Garcia-Planas</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Victoria%20Garcia-Camba"> Maria Victoria Garcia-Camba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of brain stem auditory evoked potential (BAEP) is a common way to study the auditory function of people, a way to learn the functionality of a part of the brain neuronal groups that intervene in the learning process by studying the behaviour of wave VI.

Objective preconditions for entrepreneurship are developed by the market economy that should stimulate entrepreneurship by allowing the use of economic opportunities for all those who want to do business in respective field while providing guarantees to all owners and creating a stable business environment for entrepreneurs. Subjective preconditions of entrepreneurship are formed primarily by personal characteristics of the entrepreneur. These are his properties, abilities, skills, physiological, and psychological preconditions which may be inherited, inborn or sequentially developed and obtained during his life on the basis of education and influences of surrounding environment. The paper is dealing with issues of objective and subjective preconditions for entrepreneurship and provides their analysis in view of the current situation in Slovakia. It presents risks of the business environment in Slovakia that the Slovak managers considered the most significant in 2014 and defines the dominant attributes of the entrepreneur in the current business environment in Slovakia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=innovations" title=" innovations"> innovations</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunity" title=" opportunity"> opportunity</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/19333/objective-and-subjective-preconditions-for-entrepreneurship-from-the-point-of-view-of-enterprise-risk-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">523</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1115</span> Chromosomal Damage in Human Lymphocytes by Ultraviolet Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Osorio%20Ospina">Felipe Osorio Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Adelaida%20Mejia%20Arango"> Maria Adelaida Mejia Arango</a>, <a href="https://publications.waset.org/abstracts/search?q=Esteban%20On%C3%A9simo%20Vallejo%20Agudelo"> Esteban Onésimo Vallejo Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Luc%C3%ADa%20D%C3%A1vila%20Osorio"> Victoria Lucía Dávila Osorio</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20Sanchez"> Lina María Martínez Sanchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Andr%C3%A9s%20Agudelo%20V%C3%A9lez"> Camilo Andrés Agudelo Vélez</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngela%20Maria%20Londo%C3%B1o%20Garc%C3%ADa"> Ángela Maria Londoño García</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Cristina%20Ortiz%20Trujillo"> Isabel Cristina Ortiz Trujillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive exposure to ultraviolet radiation, has shown to be a risk factor for photodamage, alteration of the immune mechanisms to recognize malignant cells and cutaneous pro-inflamatorios States and skin cancers.

In persons who practice sport, its prevalence is 36.1% (95% CI 26.5%-46.8%) and varies as it seems to depend on the intensity of exercise, movements, and impact on the ground. Such high impact sports are likely to generate higher intra-abdominal pressures and leading to pelvic floor muscle weakness. Even though the emphasis of this research is on female athletes, all women should perform pelvic floor muscle exercises as a part of their general physical exercise. Pelvic floor exercises are generally considered the first treatment against urinary incontinence. Objective: The main objective of the present study was to determine the knowledge of the pelvic floor and of the UI in elite athletes and know if they incorporate pelvic floor strengthening in their training. Methods: This was an observational study conducted on 754 elite athletes. After collecting questions about the pelvic floor, UI, and sport-related data, participants completed the questionnaire International Consultation on Incontinence Questionnaire-UI Short-Form (ICIQ-SF). Results: 57.3% of the athletes reflect not having knowledge of their pelvic floor, 48.3% do not know what strengthening exercises are, and around 90% have never practiced them. 78.1% (n=589) of all elite athletes do not include pelvic floor exercises in their training. Of the elite athletes surveyed, 33% had UI according to ICIQ-SF (mean age 23.75 ± 7.74 years). In response to the question 'Do you think you have or have had UI?', Only 9% of the 754 elite athletes admitted they presently had UI, and 13.3% indicated they had had UI at some time. However, 22.7% (n=171) reported they had experienced urine leakage while training. Of the athletes who indicated they did not have UI in the ICIQ-SF, 25.7% stated they did experience urine leakage during training (χ² [1] = 265.56; p < 0.001). Further, 12.3% of the athletes who considered they did not have UI and 60% of those who admitted they had had UI on some occasion stated they had suffered some urine leakage in the past 3 months (χ² [1] = 287.59; p < 0.001). Conclusions: There is a lack of knowledge about UI in sport. Through the use of validated questionnaires, we observed a UI prevalence of 33%, and 22.7% reported they experienced urine leakage while training. These figures contrast with only 9% of athletes who reported they had or had in the past had UI. This discrepancy could reflect the great lack of knowledge about UI in sports and that sometimes an athlete may consider that urine leakage is normal and a consequence of the demands of training. These data support the idea that coaches, physiotherapists, and other professionals involved in maximizing the performance of athletes should include pelvic floor muscle exercises in their training programs. Measures such as this could help to prevent UI during training and could be a starting point for future studies designed to develop adequate prevention and treatment strategies for this embarrassing problem affecting young athletes, both male and female. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=athletes" title="athletes">athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=pelvic%20floor" title=" pelvic floor"> pelvic floor</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=sport" title=" sport"> sport</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20incontinence" title=" urinary incontinence"> urinary incontinence</a> </p> <a href="https://publications.waset.org/abstracts/132199/pelvic-floor-training-in-elite-athletes-fact-or-fiction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132199.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1112</span> Urinary Incontinence and Performance in Elite Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Barba%C3%B1o%20Acevedo%20G%C3%B3mez">María Barbaño Acevedo Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Sonsoles%20Rodr%C3%ADguez%20L%C3%B3pez"> Elena Sonsoles Rodríguez López</a>, <a href="https://publications.waset.org/abstracts/search?q=Sof%C3%ADa%20Olivia%20Calvo%20Moreno"> Sofía Olivia Calvo Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngel%20Basas%20Garc%C3%ADa"> Ángel Basas García</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Ram%C3%ADRez%20Parenteau"> Christophe RamíRez Parenteau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Urinary incontinence (UI) is defined as the involuntary leakage of urine. In persons who practice sport, its prevalence is 36.1% (95% CI 26.5% –46.8%) and varies as it seems to depend on the intensity of exercise, movements and impact on the ground. Such high impact sports are likely to generate higher intra-abdominal pressures and leading to pelvic floor muscle weakness. Although physical exercise reduces the risk of suffering from many diseases the mentality of an elite athlete is not to optimize their health, achieving their goals can put their health at risk. Furthermore, feeling or suffering from any discomfort during training seems to be normal within the elite sport demands. Objective: The main objective of the present study was to know the effects of UI in sports performance in athletes. Methods: This was an observational study conducted in 754 elite athletes. After collecting questions about pelvic floor, UI and sport-related data, participants completed the questionnaire International Consultation on Incontinence Questionnaire-UI Short- Form (ICIQ-SF) and ISI (index of incontinence severity). Results: 48.8% of the athletes declare having losses also in rest, preseason and / or competition (χ2 [3] = 3.64; p = 0.302), being the competition period (29.1%) the most frequent where suffer from urine leakage. Of the elite athletes surveyed, 33% had UI according ICIQ-SF (mean age 23.75 ± 7.74 years). Elite athletes with UI (5.31 ± 1.07 days) dedicate significantly more days per week to training [M = 0.28; 95% CI = 0.08-0.48; t (752) = 2.78; p = 0.005] than those without UI. Regarding frequency, 59.7% lose urine once a week, 25.6% lose urine more than 3 times a week, and 14.7% daily. Based on the amount, approximately 15% claim to lose a moderate and abundant. Athletes with the highest number of urine leaks during their training, the UI affects them more in their daily life (r = 0.259; p = 0.001), they present a greater number of losses in their day to day (r = 0.341; p <0.001 ) and greater severity of UI (r = 0.341; p <0.001). Conclusions: Athletes consider that UI affects them negatively in their daily routine, 30.9% affirm having a severity between moderate and severe in their daily routine, and 29.1% loss urine in competition period. An interesting fact is that more than half of the samples collected were elite athletes who compete at the highest level (Olympic Games, World and European Championship), the dedication to sport occupies a big piece in their life. The most frequent period where athletes suffers urine leakage is in competition and there are many emotions that athletes manage to get their best performance, if we add urine losses in that moments it is possible that their performance could be affected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=athletes" title="athletes">athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=sport" title=" sport"> sport</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20incontinence" title=" urinary incontinence"> urinary incontinence</a> </p> <a href="https://publications.waset.org/abstracts/133142/urinary-incontinence-and-performance-in-elite-athletes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133142.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1111</span> The Culex Pipiens Niche: Assessment with Climatic and Physiographic Variables via a Geographic Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20C.%20Proen%C3%A7a">Maria C.

Focus is on the mosquito females; the characterization of its habitat is the key for the planning of chirurgical non-aggressive prophylactic countermeasures to avoid ambient degradation. The GIS allow for the spatial determination of the zones were the mosquito mean captures has been above average; using the meteorological values at these coordinates, the limits of each parameter are identified/computed. The meteorological parameters measured at the net of weather stations all over the country are averaged by month and interpolated to produce raster maps that can be segmented according to the thresholds obtained for each parameter. The intersection of the maps obtained for each month show the evolution of the area favorable to the species through the mosquito season, which is from May to October at these latitudes. In parallel, mean and above average captures were related to the physiographic parameters. Three levels of risk could be identified for each parameter, using above average captures as an index. The results were applied to the suitability meteorological maps of each month. The Culex pipiens critical niche is delimited, reflecting the critical areas and the level of risk for transmission of the pathogens to which they are competent vectors (West Nile virus, iridoviruses, rheoviruses and parvoviruses). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Culex%20pipiens" title="Culex pipiens">Culex pipiens</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20niche" title=" ecological niche"> ecological niche</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/16376/the-culex-pipiens-niche-assessment-with-climatic-and-physiographic-variables-via-a-geographic-information-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16376.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">544</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1110</span> Microstructure Analysis of Biopolymer Mixture (Chia-Gelatin) by Laser Confocal Microscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Flores%20Huicochea">Emmanuel Flores Huicochea</a>, <a href="https://publications.waset.org/abstracts/search?q=Guadalupe%20Borja%20Mendiola"> Guadalupe Borja Mendiola</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacqueline%20Flores%20Lopez"> Jacqueline Flores Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodolfo%20Rendon%20Villalobos"> Rodolfo Rendon Villalobos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The usual procedure to investigate the properties of biodegradable films has been to prepare the film, measure the mechanical or transport properties and then decide whether the mixture has better properties than the individual components, instead of investigating whether the mixture has biopolymer-biopolymer interaction, then prepare the film and finally measure the properties of the film. The work investigates the presence of interaction biopolymer-biopolymer in a mixture of chia biopolymer and gelatin using Laser Confocal Microscopy (LCM). Previously, the chia biopolymer was obtained from chia seed. CML analysis of mixtures of chia biopolymer-gelatin without Na⁺ ions exhibited aggregates of different size, in the range of 100-400 μm, of defined color, for the two colors, but no mixing of color was observed. The increased of gelatin in the mixture decreases the size and number of aggregates. The tridimensional microstructure reveled that there are two layers of biopolymers, chia and gelatin well defined. The mixture chia biopolymer-gelatin with 10 mM Na⁺ and with a ratio 75:25 (chia-gelatin) showed lower aggregated size than others mixture with and without ions. This result could be explained because the chia biopolymer is a polyelectrolyte and the added sodium ions reduce the molecular rigidity by neutralizing the negative charges that the chia biopolymer possesses and therefore a better biopolymer-biopolymer interaction is allowed between the biopolymer of chia and gelatin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolymer-biopolymer%20interaction" title="biopolymer-biopolymer interaction">biopolymer-biopolymer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=confocal%20laser%20microscopy" title=" confocal laser microscopy"> confocal laser microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=CLM" title=" CLM"> CLM</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=mixture%20chia-gelatin" title=" mixture chia-gelatin"> mixture chia-gelatin</a> </p> <a href="https://publications.waset.org/abstracts/82302/microstructure-analysis-of-biopolymer-mixture-chia-gelatin-by-laser-confocal-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1109</span> Characterization of Chest Pain in Patients Consulting to the Emergency Department of a Health Institution High Level of Complexity during 2014-2015, Medellin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Iv%C3%A1n%20Ba%C3%B1ol-Betancur">Jorge Iván Bañol-Betancur</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez-S%C3%A1nchez"> Lina María Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez-G%C3%A1zquez"> María de los Ángeles Rodríguez-Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Estefan%C3%ADa%20Bahamonde-Olaya"> Estefanía Bahamonde-Olaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Mar%C3%ADa%20Guti%C3%A9rrez-Tamayo"> Ana María Gutiérrez-Tamayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Isabel%20Jaramillo-Jaramillo"> Laura Isabel Jaramillo-Jaramillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mej%C3%ADa"> Camilo Ruiz-Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Morales-Quintero"> Natalia Morales-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute chest pain is a distressing sensation between the diaphragm and the base of the neck and it represents a diagnostic challenge for any physician in the emergency department. Objective: To establish the main clinical and epidemiological characteristics of patients who present with chest pain to the emergency department in a private clinic from the city of Medellin, during 2014-2015. Methods: Cross-sectional retrospective observational study. Population and sample were patients who consulted for chest pain in the emergency department who met the eligibility criteria. The information was analyzed in SPSS program vr.21; qualitative variables were described through relative frequencies, and the quantitative through mean and standard deviation ‬or medians according to their distribution in the study population. Results: A total of 231 patients were evaluated, the mean age was 49.5 ± 19.9 years, 56.7% were females. The most frequent pathological antecedents were hypertension 35.5%, diabetes 10,8%, dyslipidemia 10.4% and coronary disease 5.2%. Regarding pain features, in 40.3% of the patients the pain began abruptly, in 38.2% it had a precordial location, for 20% of the cases physical activity acted as a trigger, and 60.6% was oppressive. Costochondritis was the most common cause of chest pain among patients with an established etiologic diagnosis, representing the 18.2%. Conclusions: Although the clinical features of pain reported coincide with the clinical presentation of an acute coronary syndrome, the most common cause of chest pain in study population was costochondritis instead, indicating that it is a differential diagnostic in the approach of patients with pain acute chest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20coronary%20syndrome" title="acute coronary syndrome">acute coronary syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20pain" title=" chest pain"> chest pain</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=osteochondritis" title=" osteochondritis"> osteochondritis</a> </p> <a href="https://publications.waset.org/abstracts/71857/characterization-of-chest-pain-in-patients-consulting-to-the-emergency-department-of-a-health-institution-high-level-of-complexity-during-2014-2015-medellin-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71857.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1108</span> Static Light Scattering Method for the Analysis of Raw Cow's Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Villa-Cruz">V.

This method is based on the analysis of the dispersion of light laser produced by a set of particles in solution. Based on the above, raw milk, which contains particles of fat globules, with a diameter of 2000 nm and particles of micelles of protein with 300 nm in diameter were analyzed. For this, dilutions of commercial milk were made (1.0%, 2.0% and 3.3%) to obtain a pattern of laser light scattering and also made measurements of raw cow's milk. Readings were taken in a sweep initial angle 10° to 170°, results were analyzed with the program OriginPro 7. The SLS method gives us an estimate of the percentage of fat content in milk samples. It can be concluded that the SLS method, is a quick method of analysis to detect adulteration in raw cow's milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=light%20scattering" title="light scattering">light scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20analysis" title=" milk analysis"> milk analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=adulteration%20in%20milk" title=" adulteration in milk"> adulteration in milk</a>, <a href="https://publications.waset.org/abstracts/search?q=micelles" title=" micelles"> micelles</a>, <a href="https://publications.waset.org/abstracts/search?q=OriginPro" title=" OriginPro "> OriginPro </a> </p> <a href="https://publications.waset.org/abstracts/28216/static-light-scattering-method-for-the-analysis-of-raw-cows-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28216.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1107</span> The Role of Digital Text in School and Vernacular Literacies: Students Digital Practices at Cybercafés in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guadalupe%20L%C3%B3pez-Bonilla">Guadalupe López-Bonilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Students of all educational levels participate in literacy practices that may involve print or digital media. Scholars from the New Literacy Studies distinguish practices that fulfill institutional purposes such as those established at schools from literate practices aimed at doing other kinds of activities, such as reading instructions in order to play a video game; the first are known as institutional practices while the latter are considered vernacular literacies. When students perform these kinds of activities they engage with print and digital media according to the demands of the task. In this paper, it is aimed to discuss the results of a research project focusing on literacy practices of high school students at 10 urban cybercafés in Mexico. The main objective was to analyze the literacy practices of students performing both school tasks and vernacular literacies. The methodology included a focused ethnography with online and face to face observations of 10 high school students (5 male and 5 female) and interviews after performing each task. In the results, it is presented how students treat texts as open, dynamic and relational artifacts when engaging in vernacular literacies; while texts are conceived as closed, authoritarian and fixed documents when performing school activities. Samples of each type of activity are shown followed by a discussion of the pedagogical implications for improving school literacy. <p class="card-text"><strong>Keywords:</strong> <a
